Guppy fry bent spine

[Nomalom]

So my guppy’s have bred and I’ve had these fry for about a month now and they both have bent spine they’re both eating swimming well they just look odd. My water parameters are good they live in a 110 litre aquarium I use reverse osmosis water and the filters have been changed a couple of weeks ago other fish are good just these two. I did some reading and it said it may lead to euthanasia can anyone help me to try and avoid that option kind regards Anya.

Most likely a genetic defect; some live fairly normal lives with it, some don't

What do you mean by "changed the filters"?

As in replaced them like you should every now and then the sponges and resins

Filter media should only be replaced when it completely falls apart, which isn't often

In newer tanks (and even established ones), the beneficial bacteria you need to maintain the tank's cycle colonize on that filter media; when you toss the media, you toss the beneficial bacteria, as well, and can lose the cycle

Don't listen to advice from pet store employees, or the filter manufacturers; they are there to make $, not give good advice

We replaced it two weeks ago because it hadn’t been changed in about 2-3 months maybe just under we know what we’re doing like I’ve said all the fish are healthy apart from the guppy’s and they’re eating and swimming fine it’s just the bent spine it’s a juwel filter I also have live plants which are beneficial again like I said the water parameters are good

 

[Nomalom]

Reverse osmosis is water that has metals and chlorine taken out of it they aren’t the filters in the fish tank it’s what makes water safe to go in fish tanks

 

[Slaphppy7]

Fish expel waste; the waste contains ammonia; the beneficial bacteria consume this ammonia, making the water non-toxic

RO water contains almost no general hardness (gh); guppies are hard water fish

Well, this means bad genetics. Probably the mother or the father had too much inbreeding in their bloodline. or just bad genetics, what I've already mentioned.
Sometimes it also happens when they're offered bad nutritious food. Burt that happens more when they're older. So, I do think we can rule that out.
When they have a bent spine like this, they'll grow up healthy in general. They'll swim okay and they'll eat fine. Buit if it will worsen (that can happen sometimes), and you'll see that their swimming ability will go bad, I'd help them out and eliminate them. But from experience, most won't get worse. And in that case, they'll have a normal lifespan.
